A Noble Radiance – Donna Leon

In a village in the Italian Dolomites a farmer ploughs up a young man’s body. When a signet ring suggests he’s the kidnapped son of a family of Venetian merchant aristocrats, Commissario Brunetti naturally seeks insights from his father in law.

A really good read, combining the main plot with the self-serving political machinations always in play within the Questura and the three loves of Commissario Brunetti’s life: justice, food and family.
